TYPOGRAPHIC COMPOSING-MACHINE.

Application filed March 12,

To all whom it may concern Be it known that I, JOSEPH FRENCH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Typographic Composing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to improvements in justification indicator mechanism for typographic machines and has for its principal object to facilitate the reading of the index, to which end the invention consists in the construction, arrangement and combination of parts hereinafter fully described, the novel features being specified in the appended claims.

In the accompanying drawings illustrating a preferred form of embodiment, Figure 1 is a front elevation of the line measuring and justification indicating mechanism of a typographic composing machine with the improved attachment applied thereto. Fig. 2 is a top plan view of the attachment shown in connection with the indicator drum. Fig. 3 is a perspective of the attachment viewed from the inner or rear side. Fig. 4 is a horizontal sectional view of the attachment. Fig. 5 is a detail view of the pointer holder with a section of the pointer therein. Fig. 6 is a detail view showing the means for locking the swinging frame to the vernier scale support. Fig. 7 is a diagrammatic view illustrating the action of the lens in enlarging the figures of the scale.

The same numerals designate like parts in the several views. I

The invention is illustrated as applied to the record strip composing machine of Patent No. 944,405, dated December 28, 1909, to which reference is had for a detailed description of the construction and operation of the composing machine proper. It will suffice for present purposes to designate some of the principal elements of said machine, such as the units wheel 1, holding pawl 2, units rack 3, stop bars 4, motor rack 5, motor cylinder 6, motor return cylinder 7, indicator drum 8, transmitting gears 9 be Specification of Letters Patent.

tween the indicator drum and motor rack, line scale rack 5", and the pointer carrier 10, the latter connected to and forming part of the space registering mechanism. During its measured advance motor rack 5 picks up and communicates its motion through transmitting gears 9 to the indicator drum 8, the latter carrying a chart divided by two series of parallel lineslongitudinal and circumferential-into squares each containing one or more, usually two, signal indicia designating the justification signals or keys appropriate to different lengths of line and the numbers of justifying components contained in the line. The presentation of the several circumferential divisions is determined by the line measuring mechanism and of the longitudinal divisions by the space registering devices acting through carrier 10 upon a pointer coupled with the latter. Commercial machines of this class are oftwo kinds, the one provided with single line measuring, space registering and indicator devices, and the other provided with two sets of said mechanism adapted for simultaneous or dissimultaneous action and controlled from a single keybank, after the manner described in Patent No. 925,073, dated June 15, 1909.

Owing to speed requirements the indicator drum must needs be light in weight and as small in dimensions as is consistent with the number of divisions and size of the figures. In practice it is customary to make the divisions approximately "1 wide and 9;" high, and to insert in each division two figures, one above the other, ranging from one to fifteen each representing a separate factor of the justification signal. This means that the figures must be small and, under conditions of use, more or less difiicult for the operator to read, thus affording a fruitful field for mistakes in justification which are only developed and made plain when the record strip is run through the performing member, to-wit, the type casting and composing machine of which the produced record strip is the controller.

The present invention is designed to afford a ready means, in the form of an attachment to the composing machine, for both illuminating and magnifying that portion only of the scale where the reading is to be made, and to enable said attachment to be applied and adjusted to either kind of machine, 2'. (2.; to; the single or' the doabl iii-1 dicator machine and toeither member of the double machine. T this end the cap 11 of the bracket supporting motor cylinder 6 is formed or provided with a pivot post 12 for receiving the bearing 13 of the plate or bracket 14, the latter furnished with a shoulder 15 in position to engage a stop 16 on cap 11 when saidplate is swung outward or away from drum 8, and with'a notched por-.

tion or latch 17 in position to engage the support 18 of the Vernier scale '19 when said plate is swunginward or toward the indicator drum for retaining the attachment in operative position. This swinging move-'- ment of the :plate is designed to--facili-tate the adjustment of the supported members hereinafterreferred to and to uncover the drum support when it is desired to insert or remove the drum. "The-vertical movement= of bearing 13 on post 12 permits the engagement and disengagement of latchli', whilea screw 20 carried by-post-JQ serves to -detachably securethebracket in .position there-:

on and prevent aecidental displacement. L I Detachably and adjustably secured to I whracket 14v is a frameor housing'composed of top and-bottom plates 21, 22, united by: a tubular metal casing 23 and by two verti---. cal plates 24,25, the latter spaced to afford a vertical slit or sight opening which is :ren-

. .dered adjustable in width by the application" of a laterally adjustable plate QTtOjVGIt'lCitl plate 24. The inner side-of casing 23'is-pro vided with a longitudinal slot or opening 28 and within said casing is fitted a tubular lining 29 preferably of asbestos. The upper end of casing 23 is openand forms a-socket for the reception of a detachable electric" lamp holder 30, the lightrays -fronrwhioh are directed through opening 28 *upon'the longitudinal section of the indicatord'rurn containing the indicia appertaining to"th'e"- position of adjustment-effected by the'l'ine measuring mechanism. Openings 31 areprovided in the upper end of casing23 for-the escape of heated 'air. The-sight openingis covered by a cylindrical lens '32 the axis" whereof is parallel with the axis of the indi-- cator drum, said lens resting against theouter face of plates 25 and 27, positioned by "a shoulder on plate 25 and the edge of plate' what with the kind of machine.

from plates i I To render the attachment applicable for use in any one of the three positions indicated and to either kind of machine, the pointer 34 cooperating With the indicator drum, is arranged for adjustment circumferentially of the drum (as by providing it with a curved shank 35 concentric or nearly so .with the drum and securing the same in a horizontal direction within a clamp 36 carried by. a headl? on the carrier 10) and the lens and light housing is also arranged for adjustment upon its supporting bracket on a line substantially concentric with the surface :of the drum 509215 to preserve the' proper focal distance-of the lens, as by providing the bracket with a plurality of equally spaced seats38 and the lower plate 22 with' correspondingly spaced openings for the=reception of screws 89'. 1

In Fig. 2 the attachment is shown applied to asingle machine wherein the line of vision" is represented-by thelb'roken line radiating from the axis-of the drum, in which case the screws are applied to the two interme diate bearings, and by shifting the housing to the right so that the two screw holes regis- 4 i ter with thetwo right hand bearings it will be set for the left indicator drum and 'byshifting it in the opposite direction toregister with thetwo left hand bearings it will beset for the right hand drum of the double machine; -As thus constructed the attiichment when applied to the machine provides;

for an effective illumination of thesection of the drum containing the column of figures pertaining' to the lengthof line and oi the pointer for designating the division of the" section appropriateto the number of justifi-' cation space type recorded in the line 'with out at the sametime illuminating'unnecessarily otherparts of the machine or presenting the light in a pos ition to irritate theeyes of the operator .or distract his attentionfromcopy as would be tlie'case if an efiee tive'shield' such-as described was not pro vided and by the use of the cylindricallens' the characters which are necessarily made small are'magnified' as'illustrated in Fig. 7 i thus enabling them to be readily observed." Plate=27 in rear of the lens'is also provided E with figures which read in connection with the pointer indicate the number of justifying space type which have been incorporated among the signals composinga line. The illuminated lens is further utilized as a substitute for thesignal bell foradvising the tion to be alternately engaged durin the reciprocation of the line scale rack. hen the line measuring mechanism is reset preliminary to the composition of a line, rack 5" is moved to an extreme position to the left, Fig. 1, and arrested at the beginning of the line measure. During this retrograde movement the left arm 42 is engaged to shift member 41 to open position, thereby extinguishing the lamp. This shift of member 41 takes place as the rack is leaving the justification area and has the effect of proj ecting the right arm 42 into the path of pin 40, so that upon the reverse orameasurmg movement of rack 5 said pin willengage the right arm 42 and close the switch as the rack 5" enters the justification area. The action of the switch may be expedited by the application of a spring 44 to an arm 45 carried by member 41, said spring acting to impel the arm in either direction as the latter passes the center and to hold the same in either position, open or closed, preliminary to the rengagement of pin 40.
